Notes

Plan of analytical attack

1. DOES INVERT COMMUNITY VARY WITH HABITAT?

• NMDS of traps, vectors for veg and land use
• Multivariate GLMM:

taxa abundances ~ land use + veg + RANDOM:site

2. DOES LIZARD DIET VARY WITH HABITAT?

• NMDS of lizards, vectors for veg and land use
• Multivariate GLMM:

taxa abundances ~ land use + veg + RANDOM:site

Combine pitfall/sticky data?
Use rel abundance or PA?
Is it fine to use a trap/lizard as a sample, with site as a RE?
Remove rare taxa (limit to top 8 prey items)?

3. DOES INVERT COMMUNITY PREDICT LIZARD DIET?

• Multivariate GLMM:

diet abundances ~ prey abundances + RANDOM:site

Is this even a thing you can do???

4. WHAT ABOUT PLANTS AND ANTS?

• Something simple about herbivory/myrmecophagy because it’s especially weird/interesting

Other ideas

• Diversity/abundance
• Invert biomass
• Invert functional groups (e.g. hardness, activity level)
• Prey selectivity indices

Qs 4 Colin

• Land use gradient instead of binary?

To do:

• Separate ants using comments
• Flag rare OTUs
